Well...
how much it has to be explained same thing? wPvP doesn't need rewards, it's
spontaneous and unplanned process (at least from one side, since combat is not a “demand”, but a free choice in a closed world, but when both parties know that the only rule of this world requires fight, it cancels freedom of choice, and therefore everything else about "wPvP") arising from banal clash of interests, curiosity and is carried out on rules of the world, where it happens (without seams, solid, taking into account world NPC's and area geography, professions/"silly" items and attracting passers-by, without choice toggles)... and now
attention!
WM isn't wPvP.
It has completely different rules, another organization.
"Organized” clashes occurring in designated areas, planned by devs (in fact, this is BG, but not a war for resources or a temporary place of deployment), such as defending a castle/war profit&gain&reward
documented by game isn't wPvP for exactly same reason, but conditional “caravans/travelers robbery/killing” is the things what you're talking about... but not the stuff you want.
When will you understand this? Don't interpret/perceive WM as wPvP, because it's not, never was and, judging lack of understanding among devs in this matter, will never be.
PvP servers are wPvP, but not WM - it's just a fight territory with duplication of quests and world (which basically just for scenery) which designed to give you rewards for this activity, it doesn't ask about
your choice, just comand/demand the war.
You don't need WM for wPvP, you don't need rewards for wPvP, you'll be disturbed by shards/mode-toggle/phasing/CRZ during wPvP, you need closed servers with rules that allow this wPvP to exist. That's all! But now you are deprived of such, and no matter how much you whine about injustice of life, this won't change facts above.
If you want (guilds')war for hubs/castles - ask for them to be designed! If you want balanced groups within a specific territory, even with PvE stuff - ask about BG *point on AV* or some kind of $hitty Ashran! All that is required of you is not to ask wPvP from devs, but specific stuff, because they don't even clearly understand what you want from them! Do you know why? Because you yourself are the ones, who don't ...in the end, what you're asking for has taken place also in vanilla and BC, WotLK had a couple of such territories, but it was all “organized/documented and it was rewarded”, which means again that it wasn’t... what? pure wPvP! At least it was without shards/mode-toggle/phasing/CRZ disgrace *hush angrily*
